I had that happen to me but my fix would not be something I'd suggest to a user, as I just deleted everything - runtimes and all - and did a clean install and update. 

 

If you are experiencing an issue with the updaters and SR's you should contact Smith Micro Software Tech Support. Much of the staff is out this week but there are still a few TS guys around who can probably find a simpler solution for you guys. Also, voicing the problem will probably make us take a look at the steps involved in updating both and how we can better clarify it for you end users. So please, if you're still having a problem, contact tech support. 

 

And Happy New Year...can't believe it's 2014. Where are my flying cars?
